Changelog

Changes since release version 1.14.6

Corrections:

#MCP-4761: WUI prompt "Invalid value type" when attempt to enable STUN server with TCP or TLS transport

The M500 WUI (System → SIP Account Management → Account x → Signaling) no longer gives an "invalid value type" error message if the user selects Enable STUN and selects Transport other than "UDP".

STUN always uses UDP. The Transport field (parameter sip_account.x.transport_mode) only affects SIP signaling.

Other Corrections

Reference	Description
#MCP-5754	Shared directory exists on the handset after resetting the base.
#MCP-5755	Device incorrectly used a private IP in STUN mode after reboot when the shared SIP port was enabled.
